NTSB summary
HISTORY OF FLIGHT On February 2, 2011, about 1729 eastern standard time, a Potez-Air Fouga CM 170 Magister, N415FM, was substantially damaged when it impacted terrain during a traffic pattern approach to landing at Kissimmee Gateway Airport (ISM), Kissimmee, Florida. The certificated commercial pilot/owner, and the certificated commercial pilot/mechanic were fatally injured. Visual meteorological conditions prevailed. The flight was not operating on flight plan during the local 14 Code of Federal Regulations Part 91 maintenance test flight. According to a work order, the flight was being conducted subsequent to the repair of a number of hydraulic leaks. Federal Aviation Administration (FAA) air traffic control tower transcripts and voice tape information were combined with radar data to produce a sequence of events. Tower transcript times and the more-accurate radar return times did not match, with the tower time of the accident occurring just before 1733:21, and the airplane's last radar return occurring at 1728:52. According to a police officer, he also observed the airplane in the landing pattern at 1728. Although not exact, a 4 minute, 30 second adjustment was applied to the tower transcript times to more accurately reflect actual transmission times: At 1705, a pilot, whose voice was identified by a close friend as that of the pilot/mechanic, and whose voice was heard on all subsequent transmissions, called for taxi, and stated: "I'm unfamiliar with the airport." The ground controller then provided progressive taxi instructions to runway 24. At 1717, the airplane was cl
Probable cause
The pilot/mechanic's improper decision to continue a tight-turning landing pattern after a loss of hydraulic pressure, and his subsequent failure to maintain adequate airspeed during that pattern, which resulted in an accelerated maneuver stall. Contributing to the accident was a loss of hydraulic pressure after the extension of the landing gear.
